Package: notmuch
Version: 0.37-1

The attached message has a bunch of RFC-2047-encoded special characters 
in the display-name part of the From field:

    $ grep ^From: weird-from.eml
    From: =?UTF-8?Q?=3Cfoo=40example.org=3E=2C?= <bar@example.org>

When you show this message in notmuch, the special characters show up 
unquoted (and unencoded), so that it looks like there are two addresses 
in the From field:

    $ ./notmuch-show-from < weird-from.eml
    From: <foo@example.org>, <bar@example.org>

I initially thought this is a GMime bug, but it seems GMime gets this 
right:

    $ ./gmime-show-from < weird-from.eml
    From: "<foo@example.org>," <bar@example.org>
